Interface JMXTableSupport

All Known Subinterfaces:

JMXMutableTableSupport

All Known Implementing Classes:

AbstractJMXTableSupport, MBeanAttributeMOTableSupport

public interface JMXTableSupport

The JMXTableSupport defines the necessary interface to map tabular JMX data to a SNMP4J-Agent table model. The interface takes care of mapping JMX row identifiers to SNMP table indexes and vice versa.

Method Detail

mapToIndex

org.snmp4j.smi.OID mapToIndex(org.snmp4j.smi.OID tableOID,
                            Object nativeRowID,
                            int nativeIndex)

Maps a native MBean row identifier object or index to a SNMP table index OID.

Parameters:

tableOID - the OID of the table ManagedObject (including the .1 of the entry object) for which indexes are mapped.

nativeRowID - the native row ID object which identifies the row. If null then nativeIndex identifies the row.

nativeIndex - the native enumerating index if rows are not identified by an object.

Returns:

the SNMP row index OID (suffix).

mapToRowId

Object mapToRowId(org.snmp4j.smi.OID tableOID,
                org.snmp4j.smi.OID rowIndex)

Maps a SNMP row index to a native row identifier object.

Parameters:

tableOID - the OID of the table ManagedObject (including the .1 of the entry object) for which indexes are mapped.

rowIndex - a SNMP row index of the table specified by tableOID.

Returns:

a native row identifier.

rowIdIterator

Iterator rowIdIterator(org.snmp4j.smi.OID tableOID)

Returns an Iterator over the row identifiers of the table.

Parameters:

tableOID - the OID of the table ManagedObject (including the .1 of the entry object) for which indexes are mapped.

Returns:

an Iterator of row identifiers.

rowIdTailIterator

Iterator rowIdTailIterator(org.snmp4j.smi.OID tableOID,
                         Object firstRowId)

Returns a tail iterator over the row identifiers of the table.

Parameters:

tableOID - the OID of the table ManagedObject (including the .1 of the entry object) for which indexes are mapped.

firstRowId - the lower bound (including) of the row identifiers to return.

Returns:

an Iterator of row identifiers.

getLastIndex

org.snmp4j.smi.OID getLastIndex(org.snmp4j.smi.OID tableOID)

Gets the last SNMP index currently supported by the specified table.

Parameters:

tableOID - the OID of the table ManagedObject (including the .1 of the entry object) for which indexes are mapped.

Returns:

the last SNMP row index of the specified table.

getRowCount

int getRowCount(org.snmp4j.smi.OID tableOID)

Returns the number of rows of the specified table.

Parameters:

tableOID - the OID of the table ManagedObject (including the .1 of the entry object) for which indexes are mapped.

Returns:

the number of rows in the table.

getRow

int getRow(org.snmp4j.smi.OID tableOID,
         org.snmp4j.agent.mo.MOTableRow row)

Gets the row values for the specified row.

Parameters:

tableOID - the OID of the table ManagedObject (including the .1 of the entry object) for which indexes are mapped.

row - a MOTableRow instance which will be modified to hold the SNMP values of the row specified by row's index value.

Returns:

a SNMP error status that indicates whether to operation succeeded or not.

setRow

int setRow(org.snmp4j.smi.OID tableOID,
         org.snmp4j.agent.mo.MOTableRow row,
         int column)

Sets the value of a column (cell) of a row from the corresponding SNMP conceptual row.

Parameters:

tableOID - the OID of the table ManagedObject (including the .1 of the entry object) for which indexes are mapped.

row - a MOTableRow instance that identifies the target row by its row index (indirectly) and that contains the SNMP values that replace the corresponding native values.

column - the zero-based column index to set.

Returns:

a SNMP error status that indicates whether to operation succeeded or not.

isEmpty

boolean isEmpty(org.snmp4j.smi.OID tableOID)

Checks if the table is empty or not.

Parameters:

tableOID -

Returns:

true if the table is empty (has no rows), false/code> otherwise.
